Lactagogue pig feed applied to hypogalactia of postpartum sows and preparation method thereof

Abstract

The invention provides a lactagogue pig feed applied to hypogalactia of postpartum sows. The feed consists of the following raw materials in parts by weight: 50-100 parts of corn meal, 50-100 parts ofbran, 30-50 parts of soybean meal, 20-30 parts of black fungus powder, 10-20 parts of shrimp shell meal, 10-20 parts of fish meal, 10-20 parts of shell powder, 10-20 parts of sweet potato powder, 3-6parts of vegetable oil, 1-3 parts of edible vinegar, 1-3 parts of salt, 1-3 parts of composite trace elements, 1-3 parts of composite vitamins, and 3-5 parts of a Chinese herbal medicine additive. The invention also provides a preparation method of the feed. The lactagogue pig feed has the efficacy of tonifying qi, replenishing blood, regulating qi, promoting blood circulation, unblocking meridians and promoting lactation. The raw materials are combined, can effectively prevent and treat the occurrence of hypogalactia of postpartum sows, and can effectively improve the milkability of the sows. With the feed, litter weight at weaning of piglets at the age of 35 days is improved, and survival rate and growth speed of the piglets are obviously raised compared with control groups, so that theincome of sow farmers can be improved.

Description

technical field [0001] The invention relates to a feed for sows, in particular to a feed for lactating pigs used for postpartum lactation deficiency of sows and a preparation method thereof. Background technique [0002] Reasons for postpartum lactation in sows: 1. Improper feeding and management during pregnancy. Insufficient nutrition of sows during pregnancy will not only affect the development of the fetus, but also affect the hyperplasia of mammary glands in sows; especially in the late pregnancy, the nutritional level is too low , Insufficient energy, lack of protein feed, more likely to make sows thin, mammary gland dysplasia, dry and thin breasts. 2. Old and frail sows The sexual maturity time of sows is generally 5 months to 8 months, the suitable period for breeding is 9 months to 12 months, and the period of cessation of reproductive ability is 10 to 15 years old. Most of the sows that have been used for more than 5 years (or more than 7 to 8 litters) have reduce...

If it is not eliminated in time, it is still reserved for seeding, and there will often be insufficient milk after delivery.

3. Unbalanced nutrition during pregnancy Because the basal metabolic rate increases and the appetite is strong after the sow is pregnant, some farmers will feed a large amount of carbohydrate feed, ignoring the sufficient supply of protein and vitamins, causing the sow to accumulate too much fat. This will not only cause endocrine disorders, but also affect the development of breast acini due to excessive fat deposition in the breast.

There are many methods of artificial lactation and artificial lactation, but we must carefully analyze the reasons for the lack of mi
